GUSTAV OTTO, OF JERSEY CITY, N. J., ASSIGNOR TO THE OELLULOIDMANUFACTURING COMPANY, OF NEW YORK, N. Y.

MANUFACTURE OF PESSARIES FROM CELLULOlD AND ANALOGOUS PLASTIC MATERIAL.

SPECIFICATION forming part of Letters Patent No. 235,959, dated December28, 1880.

Application filed November 12, 1880. (No model.)

To all whom it may concern:

Be it known that I, GUSTAV OTTO, of Jersey City, in the county of Hudsonand State of New Jersey, have invented a new and useful Improvement inthe Manufacture of Pessaries from Celluloid and Analogous PlasticMaterials, of which the followiu g is a specification, reference beinghad to the accompanying drawings.

[O The invention relates to improvements in pessaries, and especially tothat class which are so formed that they may be bent to any shape, atpleasure. lessaries of this class are now made of wire coated with softrubber,

which are open to objection by reason of the fact that after they havebeen used a short time they become exceedingly offensive on account ofthe absorption of secretions, which necessitates their being discarded.Another objection which has caused great inconvenience has been that thepresence of sulphur in the rubberhas been a cause of irritation which ithas been impossible to avoid or cure.

By means of my pessary I overcome all the objections to the pessariesnow in use, and provide an instrument which is, I believe, a markedadvance upon all heretofore known.

The essential novelty of my invention consists in employing flexiblecelluloid or other other materials, whereby I produce an instrumentwhich has a highly-polished surface and is at the same time sufiicientlypliable, which may be applied without danger of pre- 3 5 judiciallyaffecting the parts with which it comesin contact,and whichmay be bentwithcompound of pyroxyline in lieu of rubber or out danger offracturingor impairing the surface. The instrument will be formed with a flexiblecore, preferably ot'copper wire, its exterior surface being highlypolished to prevent friction.

In the accompanyingdrawings I have shown a longitudinal section, Fig. 1,and a plan view, Fig. 2, of instruments embodying my invention, in whichA denotes the core composed of 5 copper wire or some other suitablematerial, and B the elastic celluloid. By preference, the instrumentwillbe so constructed that thecore can move readily within its case ofcelluloid or other compound of pyroxyline, although it is not essentialthat it should. The method of construction is a matter of judgment whichwill depend upon circumstances, and which need not be set forth herein.

I do not limit myself to any mode of manufacturc; but

What I claim as my invention, and desire to secure by Letters Patent,is-

1. A pessary composed wholly or in part of flexible celluloid or othercompound of pyroxyline.

2. A pessary composed wholly or in part of celluloid or other compoundof pyroxyline.

In testimony that I claim the foregoing improvement in manufactures ofcelluloid and 65 analogous plastic material, as above described,

I have hereunto set my hand this 12th day of November, 1880.
